MOLDING GA]? OR COVER.

Application filed October 17, 1916.

To all whom it may concern:

Be it known that I, DAVID W. BowE, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented a new and useful Molding Cap or Cover, of which the followingis a specification.

The device forming the subject matter of this application is adapted tobe employed for fashioning a post one face of which is outwardlyconvexed.

The invention aims to provide novel means whereby a convexity may beformed in one face of the post: to provide novel changes in the preciseembodiment of the invention herein disclosedcan be made within the scopeof what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, a post moldembodying the present invention, parts being broken away;

Fig. 2 is a transverse section of the structure shown in Fig. 1;

Fig. 3 is a fragmental longitudinal'section taken through the coverportion of the mold;

Fig. 4 is a cross section showing a modification of the invention; and

Fig. 5 is a fragmental longitudinal section showing a furthermodification.

In carrying out the present invention there is provided a mold 1 whichmay bemade of metal, the mold including a bottom 2 and side walls 3having outstanding flanges 4, the mold being closed at'itsends asindicated at 5.

The invention includes a cover6 which, like the mold 1 is made of metal.The cover 6 convexes outwardly, so that one face of the post formed inthe mold l'will' be given a convexity. The cover 6 fits be tween theside walls 3 of the mold 1.'

Specificationof Letters Patent. Patented Aug 14 191% Serial No; 126,158.

Any desired number of locking strips 7 may be attached to the cover 6 bymeans of securing elements 8. The locking strip 7 is bent upwardly asindicated at 9, to form a shoulder coacting with one of the side walls 3of the mold 1, the shoulder 9 being extended as shown at 10 to lie ontop of one of the flanges 4, and being under bent to form a hook 11',engaged beneath said flange 4. The locking strip 7 adjacent one end isprovided with overhanging guides 12. Mounted to reciprocate in theguides 12 is a locking strip 14" extended as shown at 140 across theother flange 40f the mold 1' and terminating in an underlying hook 15located beneath the said flange. A link 16 is pivoted at 17 to the strip14 and is pivoted'as indicated at 18 to a lever 19 having a thumb piece20whereby it may be operated, the lever 19 being pivoted at 21 to an ear22 constituting a part of the strip 7 and overhanging the said strip.

Securing elements 23 pass through the cover 6 and hold in place on theunder side of the cover,-any desired number of ribs 24.

Theseribs- 24 areadapted to form transvided with ribs 30 having thefunctions ofthe ribs 24. The ribs 30 are held inplace by securingelements 31. Attached at 32 to the cover 29'is a bar or strip 33 havingshoulders 34 which bear against the innerfaces of the extensions 27, theshoulders 34 being prolonged to form fingers 35 overhanging the flanges28.

In the modified form of the invention shown in Fig. 5', the cover isdenoted generally by the numeral 40 and'is providedwith corrugations 41which will 'form transverse ribs in the outer face of the post.

Referring to the form shown in Figs; '1 and 2, it will be obvious thatwhen the lever 19 is swung on the pivot element 21, the link 16 willdraw the member 14 toward the member 7, whereupon the hooks 11 and 15will coact with the flanges at of the mold 1 to hold the cover in place.The form shown in Fig. t is employed when it is considered unnecessaryto lock the cover 29 on the mold.

As indicated in Fig. 4:, a plurality of molds may be mounted in asupport 50 having recesses or notches 51 adapted to receive the molds.

It is to be observed that the link 16 is curved on its inner edge, so asto span the pivot element 21 whereby the lever 19 is connected with theear 22. As a consequence, when the lever 19 is swung around into theposition shown at right hand end of Fig. 1, that is, until the inneredge of the lever 16 abuts against the pivot element 21, the lockingmembers 14 and 7 will be held against relative movement in outwarddirection until such time as the-lever 19 has been swung aroundsubstantially into the position shown in the left hand end of the Fig.1.

The aggregate in a wet and plastic form is placed in the mold 1, theaggregate being in a soft condition, so soft, in fact, that it cannot betamped. The mold 1 is filled flush with its upper edge, and then isshaken down, the upper surface of the aggregate in the mold being atrifle below the upper edge of the mold. The convexed cover 6 then isplaced between the side walls 3 of the mold and is depressed. When thecover 6 is depressed, the wet aggregate flows from the sides 3 of themold toward the longitudinal center of the mold and fills the convexityin the under side of the cover 6, air passing outwardly through thevents 25. Finally, the cover 6 is held against upward movement, by thelocking mechanism provided for that purpose and hereinbefore described.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, a mold having outstanding flanges; an outwardlyconvexed cover located within the contour of the mold; locking membersextended transversely of the mold and provided with hooks engaging theflanges, one 01 said locking members being fixed; and means forproducing relative longitudinal movement between the locking members tocause the hooks to engage with the flanges.

2. A device for making posts out of fluid concrete, comprising, a moldincluding side walls; an outwardly convexed cover mounted between theside walls and depressible therebetween to cause the concrete to movetoward the center of the mold and thus to rise in the crown of thecover, the crown of the cover being provided with an air vent; and alocking means carried by the cover and engaging the mold to prevent araising of the cover by the tendency of the concrete to flow laterallyin opposite directions, the locking means constituting mechanism forlimiting the depression of the cover, whereby when the cover isdepressed to its extreme position, the crown of the cover will lie abovethe upper edges of the side walls.

3. In a device of the class described, a mold including side wallshaving outstanding flanges; an outwardly convexed cover located betweenthe side walls of the mold; a locking member secured to the cover, oneend of the locking member being provided with a shoulder engaging oneside wall, the shoulder terminating in a hook engaging one flange, theother end of the locking member being provided with guides; a secondlocking member mounted to slide in the guides and provided with a hookengaging the other flange of the mold; and means for producing relativemovement between the locking members to cause the hooks to engage theflanges of the mold.

4. In a device of the class described, a mold including side walls; anoutwardly convexed cover located between the side walls; a fixed lockingmember on the cover and provided with a hook engaging one flange, thelocking member being provided with a guide; a second locking membermounted to slide in the guide and equipped with a hook engaging theother flange; a lever pivoted to the fixed locking member; a link; andpivot elements uniting one end of the link with the second lockingmember and uniting the other end of the link with the lever intermediateits ends.

5. A device for making posts out of fluid concrete, comprising a moldincluding side walls; an outwardly convexed cover mounted between theside walls and depressible therebetween to cause the concrete to movetoward the center of the mold and to rise to the crown of the cover, thecrown of the cover being provided with an air vent; and means forlocking the cover to the mold against upward movement, to prevent araising of the cover by the tendency of the concrete to flow laterallyin opposite direction.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
